去体检时才知道有项要打的疫苗需打两剂，间隔一个月，这样就要晚交485申请材料。怕PD有变化，能否先交材料，然后再交体检表，只要材料在PD仍current时交上去，是否就没关系了？

-Yes, you can. You cannot provide the I-693 until USCIS send you RFE for it in this case. The problem is that you must send the I-693 to USCIS within 60 days after the doctor completes and signs it. Thus, the I-693 may be out of date when USCIS send you RFE. You can ask the doctor to issue a new one to you when you receive the RFE, but some docto may charge you the physical examination fee again.

还是说如果交体检表时PD不Current了递交的材料就不受审理了？

-They still process the case, but do not appove your I-485 until the priority date becomes current again.
